Lean combustion of stratified hydrogen in a constant volume chamber
Fuel, 2021Abstract To mitigate carbon emissions from the transportation sector, the application of hydrogen as a fuel for internal combustion engines was investigated. Owing to the merits of employing hydrogen in lean-burn spark-ignition engines, hydrogen stratified charge combustion (SCC) was tested in a constant-volume chamber.

Spray combustion of Jet-A and diesel fuels in a constant volume combustion chamber
Energy Conversion and Management, 2015Abstract This work investigates the spray combustion of Jet-A fuel in an optical constant-volume combustion chamber under different ambient initial conditions. Ambient temperature was varied at 800 K, 1000 K, and 1200 K and five different ambient O 2 concentrations were used, spanning 10–21%.

A New Electrode Design for Constant Volume Combustion Chamber
Volume 11: Heat Transfer and Thermal Engineering, 2020Abstract The current method of achieving center chamber ignition in the Plasma Combustion Research Laboratory’s (PCRL) Constant Volume Combustion Chamber (CVCC) utilizes either a standard or modified spark plug. The standard spark plug achieves a representation of side wall ignition (similar to a combustion engine) while modified ...

Combustion and emission characteristics of HCNG in a constant volume chamber
Journal of Mechanical Science and Technology, 2011Finding an alternative fuel and reducing environmental pollution are the main goals for future internal combustion engines. Hydrogenmethane (HCNG) is now considered an alternative fuel due to its low emission and high burning rate. An experimental study was carried out to obtain fundamental data for the combustion and emission characteristics of pre ...

A study of heat flux in a constant-volume combustion chamber
Proceedings of the Institution of Mechanical Engineers, Part D: Journal of Automobile Engineering, 2003In the production of internal combustion engines, there has been a move towards the development of high-performance engines with fuel economy, lighter weights and smaller sizes. These trends help to answer problems related to thermal load and abnormal combustion, etc., in these engines.

Microwave-assisted plasma ignition in a constant volume combustion chamber
Combustion and Flame, 2016Abstract An experimental study was carried out to investigate the effect of microwave-assisted plasma ignition on laminar flame development in a 1.4 l constant volume combustion chamber (CVCC). The microwave-assisted plasma ignition system consisted of a commercially available 2.45 GHz magnetron (700 W), a waveguide, a 3-stub tuner, a mixer and a non-

Cyclic variation in combustion in a constant volume combustion chamber.
2009Cycle to cycle variations in combustion and turbulence characteristics in a swirling flow were measured in a cylindrical vessel. The vessel was charged by rapid tangential injection using a shrouded valve for two valve lifts (7 mm and 12 mm). A premixed lean mixture of propane and air ($\phi$ = 0.8) was ignited at quarter radius from the center ...
